FIELD OF THE INVENTION

The present invention especially relates to a fused heterocyclic compound, preparation method therefor, pharmaceutical composition, and uses thereof.

PRIOR ARTS

Phosphatidylinositol 3-kinase (PI3K) is a type of intracellular phosphatidylinositol kinase that can catalyze the phosphorylation of the 3-hydroxy of phosphatidylinositol. The PI3K can be divided into type I kinase, type II kinase, and type III kinase, and the most extensively investigated one is the type I PI3Ks that can be activated by cell surface receptors. Type I PI3Ks in mammalian cells are further divided into two groups based on their structures and receptors, class Ia and class Ib, which transmits signals from tyrosine kinase-coupled receptors and G protein-coupled receptors, respectively. Class Ia PI3Ks include PI3Kα, PI3Kβ and PI3Kδ, class Ib PI3Ks include PI3Kγ (Trends Biochem. Sci., 1997, 22, 267-272). Class Ia PI3Ks are dimers of a catalytic subunit, p110, and a regulatory subunit, p85, having dual activity of lipid kinases and protein kinases (Nat. Rev. Cancer 2002, 2, 489-501), which are considered to be related to the cell proliferation, developing of cancers, immunological diseases and inflammation-relating diseases.

Existing technologies have disclosed a number of compounds as PI3K inhibitors, such as: WO2008064093, WO2007044729, WO2008127594, WO2007127183, WO2007129161, US20040266780, WO2007072163, WO2009147187, WO2009147190, WO2010120987, WO2010120994, WO2010091808, WO2011101429, WO2011041399, WO2012040634, WO2012037226, WO2012032065, WO2012007493, WO2012135160 etc.

So far there is no small molecular PI3K inhibitor in market. Therefore, it is urgent to develop an efficient medicament of the PI3Kδ inhibitor with selectivity for treating cancers, infection, inflammation and cell proliferation diseases such as autoimmune diseases.

CONTENT OF THE PRESENT INVENTION

The problem to be solved by the present invention is to provide a fused heterocyclic compound, preparation method therefor, pharmaceutical composition, and uses thereof which is totally different from the prior art. The fused heterocyclic compound of the invention as an inhibitor with selectivity against PI3Kδ can be used to prepare a medicament for treating cancers, infection, inflammation or cell proliferation diseases such as autoimmune diseases.

The present invention provides a fused heterocyclic compound represented by formula I, formula II or formula III, pharmaceutically acceptable salt, hydrate, solvate, polymorph or pro-drug thereof,
